Connecting ethernet cable to ethernet port of a router instead of to its wan port

If I accidently connect the ethernet cable of the cable modem to the ethernet(Lan) port instead of the wan port of the router[DGL 4300] would it lead to malfunction in the router or will it not?

If you mean damage the router, putting the cable from the modem in the wrong port should not do that.  However the router will not function correctly (routing traffic, NAT, etc) with the modem plugged into the wrong port.  In other words no permanent damage done but you do need to correct it.

Let me know if you have a question or need more information.

The router will keep on working, but it won't have the correct setup to provide the connected PC's with internet access. Also, both of the devices, the router and the modem will be inside the same lan and both would be acting as dhcp server to the PC's. This causes an undefined situation. But nothing will break.
